FIG. 1 illustrates an electronic device according to variousembodiments.

Referring to FIG. 1, an electronic device 101 may include a displaymodule 110 and a housing 120.

The display module 110 may display various types of information (e.g.,multimedia, text, an image, or the like) provided to a user. In variousembodiments, the display module 110 may include a touch panel capable ofdetecting a touch operation of the user, and the touch panel mayrecognize a contact touch operation or a proximity touch (e.g.,hovering) operation of the user.

The display module 110 may be mounted on and fixed to the housing 120.The housing 120 may include various components (e.g., a processor, aDDI, a touch IC, a battery, and the like) for driving the display module110. In addition, the housing 120 may include various components, suchas a communication module, a speaker module, and the like. The exteriorof the housing 120 may be formed of a nonmetallic material (e.g.,plastic), a metallic material, or the like.

A printed circuit board 130 for mounting various electrical elements(e.g., an AP, a CPU, a GPU, a memory, a communication IC, and the like)may be mounted in the housing 120. The printed circuit board 130 mayelectrically connect the electrical elements (e.g., an AP, a CPU, a GPU,a memory, a communication IC, and the like) mounted thereon and mayallow the electrical elements to be driven by electrical signals.

Referring to a sectional view taken in the direction of line I-I′ ofFIG. 1, an electrical element 150 (e.g., an AP, a CPU, a GPU, a memory,a communication IC, or the like) mounted on the printed circuit board130 may be covered with a shield can 140. The shield can 140 may coverand protect the electrical element 150 (e.g., a CPU chip or an AP chip)mounted on the printed circuit board 130. In various embodiments, theshield can 140 may be formed of a metallic material (e.g., aluminum)with a specified stiffness or higher.

In various embodiments, a gasket 135 may be disposed between a distalend of the shield can 140 and the printed circuit board 130. The gasket135 may isolate the interior of the shield can 140 from the outside.

According to various embodiments, a configuration around the shield can140 may form a cooling structure (or a cooling module) that diffusesheat generated when the electrical element 150 is driven, and lowers thetemperature of the electrical element 150. For example, in the casewhere the electrical element 150 is a CPU or an application processor,the electrical element 150 may generate a large amount of heat for arelatively short period of time when executing an application with highcomputational complexity (e.g., a high-performance game, an applicationfor taking or reproducing 4K video, or the like). The cooling structureincluding the shield can 140 may lower the temperature of the electricalelement 150 by effectively diffusing or cooling the heat generated bythe electrical element 150.

According to various embodiments, the shield can 140 may include arecess area 141 on at least a portion of an upper surface thereof (e.g.,a surface facing the housing on a rear side of the electronic device101). The recess area 141 may have the form of a groove that is formedtoward the interior of the shield can 140 from the outside or the formof a hole that is formed through the shield can 140. In the case wherethe recess area 141 has a groove form, the recess area 141 maycorrespond to a relatively thin area of the upper surface of the shieldcan 140. While FIG. 1 illustrates that the recess area 141 isimplemented in a groove form, the present disclosure is not limitedthereto.

In various embodiments, the recess area 141 may be filled with a metalstructure 160 formed of a material different from that of the shield can140. For example, the metal structure 160 may be a metal water-coolingapparatus (e.g., a heat spreader, a vapor chamber, or the like) that hasa higher thermal conductivity than the shield can 140. The metalstructure 160 may contain fluid or a phase change material (e.g., water,acetone, methanol, ethanol, or the like). The metal structure 160 mayabsorb the heat generated by the electrical element 150 and may lowerthe ambient temperature by using heat of vaporization. The metalstructure 160 may be implemented in various forms depending on the formof the shield can 140, the arrangement of the electrical element 150, orthe like.

Hereinafter, methods for effectively diffusing and cooling the heat ofthe electrical element 150 by using various forms of shield cans 140 andmetal structures 160 will be described.

FIG. 2 is a sectional view of a shield can that includes a metal plateaccording to various embodiments. FIG. 2 may be a sectional view takenin the direction of line I-I′ in FIG. 1.

Referring to FIG. 2, the shield can 140 may further include a metalplate 170 disposed between the metal structure 160 and the electricalelement 150. The metal plate 170 may primarily receive the heatgenerated by the electrical element 150 and may diffuse the heat intothe surrounding area. In addition, the metal plate 170 may transfer theheat to the metal structure 160 with high cooling performance. In anembodiment, the metal structure 160 may be directly attached (e.g.,soldered) to the metal plate 170 in the case where the recess area 141of the shield can 140 has the form of a hole. In another embodiment, themetal plate 170 may be attached to an inner surface of the shield can140 in the case where the recess area 141 of the shield can 140 has theform of a groove.

In various embodiments, the metal plate 170 may be implemented with amaterial different from that of the shield can 140. For example, theshield can 140 may be formed of aluminum, and the metal plate 170 may beformed of a copper alloy that has a higher thermal conductivity thanaluminum.

In various embodiments, a lower surface of the metal plate 170 (asurface facing the electrical element 150) may be attached to a surfaceof the electrical element 150. For example, the metal plate 170 may beattached to an upper surface of the electrical element 150 (a surfacefacing the metal plate 170) by using a heat conduction adhesive, such asthermal grease. The metal plate 170 may primarily receive the heatgenerated by the electrical element 150. The heat transferred to themetal plate 170 may be diffused into the metal structure 160 and may becooled.

In various embodiments, the metal plate 170 may be formed of the samematerial as that of the metal structure 160 or a material containingsome different compositions from those of the metal structure 160. Forexample, the metal structure 160 may be formed of copper with highthermal conductivity, and the metal plate 170 may be formed of a copperalloy.

While FIG. 2 illustrates that the metal plate 170 is implemented withone plate, the present disclosure is not limited thereto. The metalplate 170 may be implemented in various forms depending on the internalform of the shield can 140, the form or height of the electrical element150, or the like. For example, the metal plate 170 may be implementedwith a plurality of plates and may be formed such that the heightthereof in one section is different from that in another section.

FIG. 3 illustrates components outside or inside a shield can accordingto various embodiments. FIG. 3 is merely illustrative, and the presentdisclosure is not limited thereto.

Referring to FIG. 3, the recess area 141 of the shield can 140 may havethe form of a hole, and a water-cooled tube 160 a may be disposed in therecess area 141 (see a sectional view 301 or 302). The water-cooled tube160 a may include a tube-shaped pipe therein and may have fluid or aphase change material (e.g., water, acetone, methanol, ethanol, or thelike) in the pipe to cool heat transferred from the electrical element150.

A cover 180 may be disposed outside the shield can 140. The cover 180may be at least a portion of the housing 120 illustrated in FIG. 1, ormay be a case formed separately from the housing 120. The cover 180 mayprotect internal components.

According to various embodiments, the cover 180 may include a cover heatsheet 181 attached to an inner surface thereof (a surface facing theshield can 140). A user may use the electronic device 101 while a partof the user's body is brought into contact with the cover 180 as needed.In this case, the cover heat sheet 181 may disperse the heat generatedby the electrical element 150 to reduce heat transferred to the userthrough the cover 180. In various embodiments, the cover heat sheet 181may be formed of graphite.

According to various embodiments, one or more supports 182 may bedisposed between the upper surface of the shield can 140 and at least aportion of an inner surface of the cover 180 (or the cover heat sheet181). The supports 182 may allow the shield can 140 and the cover 180 tobe spaced apart from each other by a specified gap. The supports 182 mayform an air layer between the shield can 140 and the cover 180, and theair layer may additionally disperse the heat directed toward the cover180.

According to various embodiments, a thermal sheet 140 a may be attachedto the upper surface of the shield can 140 (or an upper surface of thewater-cooled tube 160 a) (see the sectional view 302). The thermal sheet140 a may disperse heat transferred to the water-cooled tube 160 a toreduce heat transferred to the cover 180. In various embodiments, thesupports 182 and the thermal sheet 140 a may be disposed between theshield can 140 and the cover 180. In this case, heat around thewater-cooled tube 160 a may be primarily dispersed through the thermalsheet 140 a and may be secondarily dispersed through the air layerbetween the shield can 140 and the cover 180.

The metal plate 170 may be disposed on the inner surface of the shieldcan 140. The metal plate 170 may be attached to an upper end of theelectrical element 150 to diffuse the heat generated by the electricalelement 150 into the surrounding area or transfer the heat to thewater-cooled tube 160 a. In various embodiments, the metal plate 170inside the shield can 140 may include a plurality of plates 170 a to 170c at different heights.

For example, the first plate 170 a may be brought into close contactwith the upper surface of the electrical element 150. The first plate170 a may have an area corresponding to the region where thewater-cooled tube 160 a is disposed. The second plate 170 b may bedisposed to surround the first plate 170 a. A distal end of the secondplate 170 b may be connected to the first plate 170 a to receive theheat generated by the electrical element 150. An upper surface of thesecond plate 170 b may be brought into close contact with the innersurface of the shield can 140. In various embodiments, the second plate170 b may be divided into a plurality of plates.

Not only the electrical element 150 generating heat but also hardwaremodules or parts 151 and 152 around the electrical element 150 may bearranged inside the shield can 140. The height of a space in the shieldcan 140 may be determined in consideration of the height of theelectrical element 150 or the heights of the hardware modules or parts151 and 152. For example, the space in the shield can 140 may be formedto be higher than the hardware modules or parts 151 and 152 in the casewhere the hardware modules or parts 151 and 152 higher than theelectrical element 150 are disposed around the electrical element 150,which is the main cause of heat. In this case, a metal block 150 b maybe disposed on the upper surface of the electrical element 150 to allowthe heat generated by the electrical element 150 to be effectivelytransferred to the first plate 170 a (see the sectional view 302). Invarious embodiments, the metal block 150 b may be formed of the samematerial as, or a material similar to, that of the water-cooled tube 160a or the metal plate 170. For example, the metal block 150 b may beformed of copper or a copper alloy.

According to various embodiments, the metal block 150 b may be attachedto the electrical element 150 through a thermal interface material (TIM)150 a.

FIG. 4 illustrates a shield can that includes a chamber type coolingstructure according to various embodiments.

Referring to FIG. 4, the recess area 141 of the shield can 140 may havethe form of a hole, and a water-cooled chamber 160 b may be disposed inthe recess area 141. The water-cooled chamber 160 b may have a largerarea and contain a larger amount of fluid or a phase change material(e.g., water, acetone, methanol, ethanol, or the like) than thewater-cooled tube 160 a in FIG. 3. The water-cooled chamber 160 b mayhave higher heat cooling performance than the water-cooled tube 160 a inFIG. 3.

The water-cooled chamber 160 b may be used 1) when the electricalelement 150 generating heat has a relatively large area, 2) when theshield can 140 has a relatively large inner space, or 3) when highcooling performance is required due to a large amount of heat generatedby the electrical element 150.

FIG. 5 illustrates a form of a shield can considering an arrangement orform of a peripheral part according to various embodiments. FIG. 5 ismerely illustrative, and the present disclosure is not limited thereto.

The amount of released heat may vary depending on a condition underwhich the user uses the electronic device 101 (e.g., the angle ordirection of a system, accessory keyboard docking, or the like), and themaximum power to be supplied within a part reliability range may varycorrespondingly. For example, the maximum power (thermal design power(TDP)) to be supplied in a range below the temperature that a CPU/GPU iscapable of resisting may be stored in advance and may be referred to asneeded.

In the case where the electronic device 101 is parallel to the directionof gravity, that is, the electronic device 101 is placed upright on thefloor, a convective heat radiation effect may be improved, which resultsin an increase in the amount of released heat. Accordingly, the maximumpower to be supplied to the CPU/GPU may be raised (e.g., 8 W). Incontrast, in the case where the electronic device 101 is in a horizontalstate, the convective heat radiation effect may be reduced, which leadsto a decrease in the maximum power (e.g., 6 W) to be supplied to theCPU/GPU.

The processor mayoutput a UI screen through which the user selects whether to adjust themaximum CPU/GPU power supply value to a vertical mode value, and mayraise the maximum CPU/GPU power supply value in response to the user'sselection.

The camera mode may be executed when a camera module operates. Arelatively large amount of CPU/GPU power supply resources may berequired and the maximum CPU/GPU power supply value may be raised whenthe camera module operates.

The inclined mode may correspond to a case where the processordetermines that the electronic device 101 is maintained at a specifiedangle for a predetermined period of time, by analyzing the angle of theelectronic device 101 using an accelerometer sensor. The processor mayoutput a UI screen through which the user selects whether to adjust themaximum CPU/GPU power supply value to an inclined mode value, and mayraise the maximum CPU/GPU power supply value in response to the user'sselection.

The horizontal mode may correspond to a case where the processordetermines that the electronic device 101 is maintained in a horizontalstate for a predetermined period of time, by analyzing the angle of theelectronic device 101 using an accelerometer sensor. The processor mayoutput a UI screen through which the user selects whether to adjust themaximum CPU/GPU power supply value to a horizontal mode value, and mayraise the maximum CPU/GPU power supply value in response to the user'sselection.

The handheld vertical mode may correspond to a case where the processordetermines that the electronic device 101 is maintained at a specifiedangle for a predetermined period of time, by determining the user'sholding state using a grip sensor and analyzing the angle of theelectronic device 101 using an accelerometer sensor. The processor mayoutput a UI screen through which the user selects whether to adjust themaximum CPU/GPU power supply value to a corresponding mode value, andmay raise the maximum CPU/GPU power supply value in response to theuser's selection.

The vertical book reading mode may correspond to a case where theprocessor determines that the electronic device 101 is maintained in avertical state for a predetermined period of time, by determining theuser's holding state using a grip sensor of a system and analyzing theangle of the electronic device 101 using an accelerometer sensor. Theprocessor may output a UI screen through which the user selects whetherto adjust the maximum CPU/GPU power supply value to a corresponding modevalue, and may raise the maximum CPU/GPU power supply value in responseto the user's selection.

The handheld horizontal mode may correspond to a case where theprocessor determines that the electronic device 101 is maintained in ahorizontal state for a predetermined period of time, by determining theuser's holding state using a grip sensor of a system and analyzing theangle of the electronic device 101 using an accelerometer sensor. Theprocessor may output a UI screen through which the user selects whetherto adjust the maximum CPU/GPU power supply value to a corresponding modevalue, and may raise the maximum CPU/GPU power supply value in responseto the user's selection.

The ON table mode may correspond to a case where the processor analyzesthe angle of the electronic device 101 by using an accelerometer sensorto determine whether the electronic device 101 is in a horizontal stateand a rear camera is hidden by a table so that the brightness of lightis maintained at a predetermine level or lower for a predeterminedperiod of time. The processor may output a UI screen through which theuser selects the maximum CPU/GPU power supply value to be an ON tablemode value, and may raise the maximum CPU/GPU power supply value inresponse to the user's selection.

In various embodiments, the processor may set different maximum powervalues in consideration of heat release characteristics of each mode.

In operation 830, the processor may supply power, based on thedetermined mode.

Referring to FIG. 9, in operation 910, the processor in the electronicdevice 101 may supply power, based on the user's sensible temperatureindex that the electronic device 101 uses.

Since users differently feel the same temperature, the processor maydetermine the user's sensible temperature index and may adjust themaximum power to be supplied, based on the determined index.

In operation 910, the processor may output a sensible temperaturesetting screen on the display thereof. The setting screen may output asurface temperature level allowed by the electronic device 101 and mayinclude an option for selecting a degree desired by the user.
